It was interesting..the entire floor of the forging shop was made of
3" thick slabs of steel..over an acre of it. They could be lifted out
for servicing the lower halves of the machines.



WOW!!! Fricken' awesome stuff.

Thought a few folks would find it interesting. I wish Id been able to
take photos when they opened an oven. Doors the size of the front of
a 2 car garage and when they opened and closed em..that end of the
mill would glow orange. They were doing a bunch of forging for
airplane parts for the gubmint. I didnt know there were that many BIG
steel parts making up the swing wing hinges and landing gear of the
big..big birds.

Id had the idea that most of an airplane is aluminum with a few steel
parts..engines and so forth. Not so!!



Do you know what they use to swing those wings? It's a thermal wax that
expands and contracts with temperature. The forces are HUGE!

Tom, do you have a website where this is described? I'm having a hard time believing it. I'm a retired airline mech. and never worked on any swing wing aircraft. Just all the big Boeings, Airbus, Lockheed etc. I did a google search and came up with nothing.

That you give it any credence shows you're a idiot. It's typical of the worthless crap Tom often posts.

I heard it from a cousin working for Loral aerospace as a design
engineer, now retired, he worked on many cool projects, a lot of which
will never see daylight. Wax motors are more common than we think. I
couldn't easily find any direct references, but I'll ask next time I
talk to him.

I believe we're talking about wax pellet temperature sensors. Those are common on older airliners. Just my .02, but I don't believe you could get any useful work from a wax motor actuator.

As it happens, he called me tonight to wish happy holidays. When I
asked him about the wax motors he said they aren't on any production
aircraft. So I apologize, I thought they were on aircraft we all would
know about. It seems they also use them on missiles and torpedoes due
to weight to force ratios and they are very precise in temp to movement.
I wish I knew more but I understand they are very powerful. Why do
you think they wouldn't do work?

Not that I think they don't work, just not in an application like an actuator for something that required large displacement like swinging the wings of an aircraft. Mr. Wilkins posted a couple of applications here that show their actual use. If I remember correctly, the 727 had a strictly mechanical sensor that prevented icing of the water coalescer bag in the air cycle cooling systems. Believe that was a wax pellet sensor. If it went bad, you'd hear the blowout bypass door banging and relieving pressure on the frozen bag.

GM used a wax actuator on the front axle interlock for the 4X4 P/Us for
many years. They worked but were S L O W in cold weather.

"Work" is force times distance. Wax-pellet actuators, which I have
seen on the vent flaps used on greenhouses, can produce a lot of force
but only through a very short distance. The wax only expands a small
percentage and that's the distance through which they're applying
force.

So it can be a lot of force but not much work.
